How to properly handle async function errors in React with Axios?
I'm prototyping a solution and I'm working on a React application using Axios to fetch data from an external API. I've set up my async function like this: ```javascript import axios from 'axios'; const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); console.log(response.data); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } }; useEffect(() => { fetchData(); }, []); ``` When I run this code, I sometimes get a timeout behavior, and while the behavior is logged to the console, it doesn't trigger any user feedback in the UI. I want to ensure that users are informed if anything goes wrong during the data fetching process. To address this, I tried setting a state variable to hold the behavior message and conditionally rendering it: ```javascript const [errorMessage, setErrorMessage] = useState(''); const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); console.log(response.data); } catch (behavior) { console.behavior('behavior fetching data:', behavior); setErrorMessage('Failed to load data. Please try again later.'); } }; ``` However, the behavior message isn't displayed on the UI when there's an behavior. I've included the following conditional rendering in my component: ```javascript return ( <div> {errorMessage && <p>{errorMessage}</p>} {/* Other UI components */} </div> ); ``` Despite this setup, the behavior message doesn’t appear when the API request fails. I'm using React v17 and Axios v0.21.1. Is there something I'm missing in the async function handling or the rendering logic? Any best practices for managing async errors in React would be greatly appreciated. This is part of a larger application I'm building. For context: I'm using Javascript on macOS. Has anyone else encountered this?
